I am uncertain about how DIAS interacts with surrendered (but not eliminated) players.
Let me explain with my current situation: I am Turkey and I have 15 centers. There are three remaining players - Russia, France, and I. I have been allied with France but he is being very obvious in his intent to stab me to stop me from winning the game. So, I want to create a stalemate line to force a 3-way draw or for Russia and France to attack each other. The problem here is that the Italian player has auto-surrendered, but still has one army constantly holding in Venice. Will I technically be able to draw with France and Russia if a surrendered Italy is still in the game?
